Granted: 2007-09-11
Abstract: To realize a reduction in the size of a cylinder block by simplifying the structure of an exhaust control valve, and to realize smooth flow of exhaust gases. There is provided an exhaust path for connecting to an exhaust port 39, comprising a first path 44 extending in a direction orthogonal to the central axis of the exhaust port 39, and a second path 43 connecting the first path 44 and the exhaust port 39, and a control valve 40 is provided in the first path 44. The rotational axis of the exhaust control valve 40 is parallel to a direction in which the first path 44 extends. The surface area of an opening 45 connecting the first path 44 and the second path 43 is variable as the exhaust control valve 40 rotates, so as to carry out control by activated heat atmosphere combustion and control of exhaust timing, etc. This makes it no longer necessary to provide a hollow section for housing an exhaust control valve at a position close to the exhaust port of the cylinder, or a bearing for supporting the exhaust control valve, and it is possible to reduce the size of a cylinder block and to realize smooth flow of exhaust gases by making the inner peripheral surface of an exhaust path smooth.

Abstract: A tamper-evident closure for a container is provided. The container is formed with means at its open upper end for making a snap fit locking connection with a cover. The container has a peripheral flange with a skirt section that surrounds and is spaced radially from the container's side wall, and the cover has a depending skirt that extends down around the upper end of the container and has a free bottom edge that lies immediately adjacent to the flange. The flange has an outer surface that is flush with the adjacent portion of the outer surface of the skirt, so that essentially the flange appear to be a continuation of the skirt. As a consequence the closure formed by the cover (lid) and the container is resistant to opening by a small child. Additionally the skirt section of the flange has a tab portion that is breakable under pressure so that, once broken, it can be depressed inwardly toward the container side wall far enough to permit a person to engage the bottom edge of the skirt on the cover and thereby force the cover off of the container. The tab portion functions as a tamper evident feature, since the fact that it has been broken can be easily discerned from inspection and since the torn tab cannot be restored to its original condition.
